UNITED STATES PATENT OFFICE.

DWIGHT ROCKWELL, OF SOUTH WINDSOR, CONNECTICUT, ASSIGNOR OF I ONE-HALF TO LUCIUS H. MATTISON, OF NEW YORK, N. Y.

ILLUMINAT'ED WIN D-VANE.'

SPECIFICATION forming part of Letters Patent No. 379.031, dated March 6. 1888.

Application filed October 14, 1887. Serial No. 262,355.

To all whom it may concern.-

. Be it known that l, DWIGHT RocKwELL, of

South Windsor, in the county of Hartford, -State of Connecticut, have invented certain new and useful Improvements in Illuminated Wind-Yanes, of which the following is aspecification.

This invention relates to improvements in wind-vanes used for showing the direction of the wind, and especially to the wind-vanes used on board of vessels.

The object of my invention is to provide a new and improved wind'vane which isilluminated, so as to be clearly visible at night.

The invention consists in a wind-vane car rying a series of luminous bodies which show clearly at night.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

In the accompanying drawings, Figure I is a side view of my illuminated wind-vane. Fig. 2 is a plan view of the under side of the same. Fig. 3 is an enlarged cross-sectional view of the same.

Similar letters of reference indicate corresponding parts.

The shaft A, which may be made of wood or metal, is provided with an aperture in which a spindle-box, B, of the usual construction is provided, the spindle C, projecting from the top of the mast D, passing through said spindle-box. The head F is secured on one end of the shaft and the wing or blade G on the other, and, if desired, a wind-bag, H,may be attached to the blade. Recesses or cavities Kare provided in the under side of the shaft, and in each of said caviticsavial, L, is placed, 0 each vial containing water and a piece of phosphorus, N.

The vials must be sealed (No model.)

absolutely tight, so as to prevent any escape of the water, as otherwise the phosphorus would lose its luminous properties. The vials are held in the cavities or recesses by means of bands 0, or by means of any other suitable devices. One vial is placed in that part of the shaft in front of the spindle and two in the part behind the spindle. At night the phosphorus in the vial is luminous and clearly shows the position of the vane.

As shown, the two vials in the rear part of the shaft are placed closer together, so as to show instantly very distinctly which is the rear part of the vane, whereby theposition of 5 5 I the vane and the direction of the wind can be seenat a glance in the darkest night.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A wind-vane containing luminous bodies, substantially as herein shown and described.

2. The combination, with a wind-vane, of

transparent receptacles on the'same and 1uminous bodies in said receptacles, substantially as herein shown and described.

3. The combination, with a wind-vane having recesses or cavities in its under side, of transparent receptacles in. said recesses and luminous bodies in said receptacles, substantially as herein shown and described.

4. A wind-vane having one luminous body held on its shaft in front of the spindle and two luminous bodies held on its shaft behind the spindle, substantially as herein shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

DWIGHT IEOCKWELL.
